Hi,

I’m creating RPM packages for:

- opinion (which includes Rails)
- ruby 1.8.4
- mongrel
- rake
- gem\_plugin
- ruby-postgres

(I want to install opinion using postgres on a RHEL system that  
doesn’t have internet access)

Do these things need rubygems also installed? Am i going to be  
breaking things (i.e. mongrel) if I don’t use rubygems?

Thanks,  
Joe

To my knowledge, gem\_plugin is the only thing on that list that  
requires rubygems. I know I’ve installed Mongrel without gems in the  
past.

Joe,

Yes, Mongrel uses a little tiny chunk of code called GemPlugins to allow  
others to extend Mongrel without having to make me add the code in.  
It’s  
already spawned Bradley Taylor’s mongrel\_cluster plugin which is helping  
many people do clustered deployments. Not including RubyGems would  
break  
this and pretty much be like disabling modules in Apache.
